11 Claims.

This invention relates to hair curling devices, and more particularly relates to novel hair curlers having means for selectively controlling bob pins used with the device.

The hair curling device of the present invention comprises a mandrel having a longitudinal slot for laterally receiving a comb insert, which when extended is used for forming a curl of hair and when inserted within the mandrel permits removal of the curl onto an attached bob pin. In accordance with the present invention, the bob pin is partially inserted into an end of the mandrel and remains inactive during the hair curling operation. When the curl is completely formed, means are provided in the device of the invention to permit the bob pin to be fully inserted into the mandrel and spread apart to receive the hair curl upon its removal from the mandrel. The hair curling tool proper is preferably of the type disclosed and in the co-pending application, Serial No. 306,040, assigned to the same assignee as is the present case.

It is accordingly an object of the present-invention to provide a novel hair curling device which receives a bob pin at one end thereof for selectively different depths of insertion.

A further object of the present invention is to provide a novel hair curling device having a slotted mandrel which receives a comb insert, and one end of which receives a bob pin for selectively different depths of insertion.

Still a further object of the present invention is to provide a novel hair curling device having a mandrel with a coacting retractable comb insert and. means for controlling the degree of insertion of a bob pin in an end of the mandrel in accordance with the position of the retractable comb insert in the mandrel.

These and further objects, advantages, and features of the present invention will appear in the subjoined detailed description of specific embodiments thereof, illustrated in the accompanying drawings in which- Figure l is a plan view of one embodiment of the hair curling device.

Figure 2 is an elevational view thereof, with the comb insert in the extended position.

Figure 3 is an elevational view of the hair curling device corresponding to Figure 2, with the mandrel portion thereof in cross-section.

Figure 8 is a cross-sectional view through the modified form of the curler, corresponding to Figure 7, with the bob pin fully inserted therein.

Figure 9 is a cross-sectional view through a further modified form of the hair curling device provided with the means for projecting, retracting and maintaining the comb of the same as disclosed in Figures 1 to 3, with the bob pin and comb insert in the extended positions.

Figure 10 is a crosssectional view through the hair curling device corresponding to Figure 9, with the bob pin in the fully inserted position and the comb insert correspondingly retracted.

The hair curling device per se may assume optional forms in practice. The general arrangement of the hair curler preferably corresponds to the form disclosed in the application Serial ,No. 306,040, previously referred to. However,-other curler forms may be employedin conjunction with thebob pin selective positioning means .to be described.

The hair curler shown in Figures 1 and 2, respectively plan and elevational views, comprises a transversely slotted mandrel it) having a comb insert II laterally coacting therewith. A thumb member l2, l3 extending from the mandrel is secured with comb H for manually changing its position from the extended and retracted positions. A regular hair comb section .l l extends from one end of mandrel t0, the same being a handle for the hair curling section of the device. The free end of mandrel l0 incorporates an acorn shaped end portion L; which in crosssection defines a ridge andvalley formation, and isprovided with a central longitudinal opening it for receiving the bob pin.

The cross-sectional view through the hair curler, Figure 3, illustrates a preferred manner for operating comb insert H with respect to iongitudinally slotted mandrel ID. A leaf spring s is positioned between the inside edge I! of retractable comb and the inside surface 18 of mandrel I6. Leaf spring 8 is arranged to mechanically bias comb insert I I normally outwardly of mandrel II] to the extended position shown in Figures 2 and 3. A cam plate 26 is arranged within thumb operated member I 2, I3, spring pressed by contained compression spring 22 against transverse pin 2| set in the shank of mandrel I6. Cam plate 20 permits lateral displacementof comb insert I I and maintains the comb insert stably in extended or retracted position.

Figure 4, a transverse cross-sectional view near the tip of the mandrel Iii, shows comb insert I I in the extended position as well as the. relatively displaced positions of central opening I6 of mandrel I0, transverse opening 32 of comb insert II, and opening 24 of portion 25 of leaf spring s.

In accordance with the present invention means are provided to limit the degree of insertion of a bob pin p mounted under tension at the mandrel end I5 until the curl of hair is Wound prior to removal from the mandrel.

Enlarged cross-sectional view Figure 5 illustrates one embodiment for carrying out the invention. End portion 25 of leaf spring a is arranged to abut tip 26 of shank 21 of bob pin p when it is inserted and maintained during curl winding in central opening I6 of mandrel I0. Comb insert II is then in the extended position, as shown, and is used for spacedly gripping the hair to curl it about mandrel I in the usual manner. The humped or sinuous shank 28 of bob pin p grips the complementary acorn end i5 of mandrel I6 under tension. The bob pin is accordingly gripped onto mandrel ID of the hair curler and held stably under tension in readiness for further coaction with the curled hair. The bob .pin is in this manner maintained out of the Way, preventing interference with the hair curling operation. 7

After the hair curl is formed about mandrel I0, indicated at 36 in Figure 6, it is ready for removal from the mandrel and gripping by bob pin p. Thumb member I2, I3 is pressed to move comb insert II to the retracted or disappearing position within the transverse slot of mandrel I6, as indicated in Figure 6. When comb insert I I is thus retracted against the pressure of leaf spring 8, itremains there due to the action of spring pressed cam plate 20 against pin 2|, as shown in Figure 3. The bottom surface I! of comb insert II straightens out leaf spring 8, as illustrated, and moves the vertical end portion 25 of the spring further within mandrel I6. 1

When comb insert II is in the fully retracted position shown in Figure 6, hole 24 of upright spring portion 25 becomes aligned with opening I6 of mandrel I 6. A longitudinal series of openings 32 of predetermined extent is arranged in the bottom'portions of a corresponding number of teeth of comb insert II, as illustrated. The tip 26 of straight shank 2'! of bob pin 22 when fully inserted willaccordingly abut the first tooth t of comb insert II having no opening 32. When the bob pin is fully inserted, its arms are spread'and extended as shown, with the humped shank 28 thereof extending angularly and over a portion of hair curl 36 preparatory to receiving the curl. The curl of hair 39 is then moved between the shanks of the bob pin, and removed from mandrel I0 to be gripped by both shanks of the bob pin as tension thereon is released to maintain it in the curled form.

Figures 7 and 8 illustrate a further form for carrying out the bob pin control feature of the the edge of. comb insert II and abuts the tip 26 of inserted bob pin p as shown in Figure 7. The projection 35 of the comb insert I I serves to limit the insertion of bob pin p in the manner of spring portion 25 of the previous form. The projection 35 is received in pocket 36 formed in the mandrel I6. Although the comb insert II, as illustrated in this embodiment, is operable for reaction by the thumb operated member I2, I3, there may be applied in this embodiment, if desired, a leaf spring to mechanically bias the comb insert nor- 1 mally outward of the mandrel II].

previously described form, in

The form of the invention of Figures 7 and 8 requires a mandrel with a relatively deeper diam eter for a given size'of comb insert than does the view of projecting portion 35. The opening I6 in mandrel I0 is accordingly eccentrically placed with respect to the longitudinal axis of the mandrel to properly coact with the series of openings 32 in comb insert II, as shown. With the comb in the retracted position of Figure 8 openings 32 of-comb insert II are opposite opening I6 of mandrel I0 and the straight shank 21 of the bob pin is permitted to be fully inserted until the tip 26 of the bob pin abuts tooth t of comb II with no opening 32. The bob pin is then ready to receive the curlof hair which is removed from the mandrel when completed, in the manner previously described.

Figures 9 and 10 illustrate a further form for carrying out the present invention. In this form a spring operated control member 40 for the bob pin is attached to the end 4| of comb insert II, adjacent the opening I6 of mandrel I I]. Member 40 limits the insertion depth of bob pin p by abutting the tip 26 thereof when comb II is in the extended position shown. Compression spring 42, extending from a recess 43 in end M of comb II, presses member 40 to the downward or abutting position. When comb insert II is in the retracted or disappearing position shown in Figure 10, abutting member 40 is displaced with respect to tip 4| of comb II due to action of com pression spring 42. When the comb is thus retracted, opening 45 in member 40, as Well as series of openings 32 of comb I I, are in alignment with central opening I6 of mandrel II). The shank 21 of bob pin 12 may then be fully inserted until its tip 26 abuts tooth t of comb II. The bob pin is then prepared to receive the curl in the manner previously set forth. The spring controlled abutting member 40 performs the selective bob pin control action without requiring an increased mandrel diameter.

It is obvious that various changes and modifications may be made to the-details of construction and arrangement illustrated without departing from the general spirit and scope of the invention as set forth in the following claims.
